GRP (Glass Reinforced Plastic), also known as fibreglass, has revolutionised stair safety in demanding environments. Here's everything you need to know about GRP stair nosings.
What Makes GRP Special?
GRP nosings combine fibreglass reinforcement with a resin matrix and anti-slip aggregate surface. The result is:
- Exceptional grip – Even in wet, oily, or icy conditions
- Corrosion resistance – Won't rust like metal
- Chemical resistance – Ideal for industrial environments
- UV stability – Colours don't fade in sunlight
- Non-conductive – Safe around electrical installations
Ideal Applications
Marine Environments
Boats, docks, and coastal installations benefit from GRP's complete resistance to saltwater corrosion.
Food & Beverage
Easy to clean and resistant to fats, oils, and cleaning chemicals.
Chemical Plants
Withstands exposure to acids, alkalis, and solvents that would destroy other materials.
Outdoor Stairs
Fire escapes, external staircases, and decking where weather resistance is essential.
Colour Options
GRP nosings come in high-visibility colours including:
- Yellow (most popular for safety)
- Black
- Green
- Grey
- Red
Yellow with black contrast strips meets visibility requirements for public buildings and workplaces.
Installation Considerations
GRP nosings are typically fixed with countersunk screws or structural adhesive. For retrofit applications, surface-mounted options are available.
The rigid nature of GRP means precise measurement is essential—unlike aluminium, it cannot be bent or adjusted on-site.
